Recommended online casinos

Will be traveling to Vegas in a couple of weeks, and will be accompanied by family, staying at Circus Circus. Never been to that casino (or that area of the strip; usually go downtown or south strip in the past), and eats look as though they may be our biggest expense (other than bankrolls!). Can anyone recommend any good breakfast and/or lunch buffets in the areas that are decent, yet will not require me to dip into my already tight trip bankroll? Would prefer buffets that are a good value (not too cheap; clean, safe, and some variety are all we ask). Willing to drive a short distance, if necessary. Evening meals will probably be where we drop some money.

Information on how to get buffet coupons would also be appreciated.

Thanks for all helpful replies; look forward to seeing you at the tables!
